Nahor (or Nachor) (Heb. נָחֹור) is the name of two persons in Torah who were both descended from Arpachshad:
- The son of Serug and father of Terah, who was the father of Abraham. According to Jubilees, his mother was Milcah daughter of Kaber, and he married 'Iyoska, daughter of Nesteg of the kin of Ur Kasdim (the son of Arpachshad for whom Ur was named). Nahor was 29 when his son Terah was born, and lived to the age of 148.
- The son of Terah and grandson of Nahor son of Serug, and the elder brother of Abraham. He married his niece Milcah, the daughter of his brother Haran and the sister of his nephew Lot. This Nahor lived in the land of his nativity on the east of the river Euphrates at Haran. He was the father of Bethuel and grandfather of Laban and Rebecca; Rebecca became the wife of Isaac son of Abraham. Nahor's great-granddaughters through Laban, Rebecca's nieces Rachel and Leah, became the wives of Jacob son of Isaac.
